Red, I am refering to MultiMin or MineralMax they contain Zinc,Manganese,Selenium and Copper. Dosage for cattle 1-2yr's....1cc/150lbs, 2yrs&older1cc/200lbs, 3wks beforebreeding and 3wks before calving.
My general feeling is that if they can eat it it is better than being injected. The only mineral I inject routinely is BoSe to calves - it contains selenium with a small amount of vitamin E as a preservative. I also govie my calves A, D, and E at birth. There is some evidence that selenium given to pregnant cows can result in abortion. ALso I have heard (but never seen( anaphylactic reactions to vitamin/mineral mixes - so I guess it would not be my first choice. Are you in an area where these minerals are deficient???
hey,DL I've heard that a cow does'nt absorb trace min through the stomach as well as one might think, i dont know. Yes,we have mineral deficiency inthis area,but who doesnt? I am aware of what happens when selenium reachs toxic levels. Thanks everone
several theories regarding minerals and their absorption, and seem to revolve around a marketing plan. what perphas is more important is the labor involved, as usual, to deliver sufficient nutrition to obtain economic goals.
Cealated (sp?)minerals was also always a sales tool. I can remember so many feed companies talking about how much better their minerals are absorbed than the competitions because of certain processes.
I just know from past feed experiences, if you give an injectable mineral shot, be careful about the levels you are then feeding. I've seen people give SE shots to lambs, then feed them a premix w/ extra selenium & end up killing them w/ SE toxicity. I'd be sure about the levels I'm feeding.
The whole mineral deal is very complicated and then add in a ruminant - wow! There is evidence (this is humans) that organic iron (like in beef) is better absorbed than inorganic iron (like in pills) - so it seems logical that different species would respond differently to different forms of minerals. Like red says chelated minerals are pretty "hot" in terms of marketing and I believe that they are more rapidly available to the ruminant - most minerals involve the use of some sort of "transporter" or a specific mechanism to be absorbed - I know there was a big push to use (perhaps a marketing push) to use injectable minerals - I pretty much use minerals that can be given by mouth (crystalyx) and give BoSe to calves....not sure that really helps ya cornbred! Like red said there is a danger of overdose - in this case more is not always better and you can kill an animal with too much.
